;
|
| 43 |
|
|
; The symbols section describing transactions was modified to contain
|
| 44 |
|
|
; several new symbol values. The reason for the change was to force the
|
| 45 |
|
|
; CA bit to be set--and remain set--once code accesses the coprocessor.
|
| 46 |
|
|
;
|
| 47 |
|
|
; Future operating systems will use the Coprocessor Active (CA) bit in
|
| 48 |
|
|
; the Old Processor Status Register to determine whether or not to save
|
| 49 |
|
|
; coprocessor state, etc.. This means that the instruction control field
|
| 50 |
|
|
; Set Coprocessor Active (SA) bit should be used as follows:
|
| 51 |
|
|
;
|
| 52 |
|
|
; (1) any coprocessor STORE must have its SA bit set to 1,
|
| 53 |
|
|
; so as to set CA,
|
| 54 |
|
|
;
|
| 55 |
|
|
; and (2) any coprocessor LOAD must have its SA bit set to 0,
|
| 56 |
|
|
; so as to prevent clearing CA.

; 1) The _cp_prec_field in the "cp_build_inst", "cp_build_inst_h"
|
| 68 |
|
|
; and "cp_build_inst_l" macros was not being defined in the case
|
| 69 |
|
|
; of Am29K-supported floating-point instructions (e.g., FADD, FSUB,
|
| 70 |
|
|
; DADD, etc.).

|
|
;
|
| 72 |

|
| 73 |
|
|
; associated with the "cp_build_inst", "cp_build_inst_h" and
|
| 74 |
|
|
; "cp_build_inst_l" macros, pertaining to the CONVERT_F_TO_D
|
| 75 |
|
|
; and CONVERT_D_TO_F instructions were incorrect.

|
|
; FUNCTION: Transfers a 32- or 64-bit operand to Am29027 input register R
|
| 637 |
|
|
;
|
| 638 |
|
|
; PARAMETERS:
|
| 639 |
|
|
; reg - the Am29000 g.p. register containing the 32-bit operand to be
|
| 640 |
|
|
; transferred, or the 32 MSBs of the 64-bit operand to be
|
| 641 |
|
|
; transferred.
|
| 642 |
|
|
;
|
| 643 |
|
|
; LSB_reg - the Am29000 g.p. register containing the 32 LSBs of the
|
| 644 |
|
|
; 64-bit operand to be transferred
|
| 645 |
|
|
;
|
| 646 |
|
|
; INT - indicates that the operand to be transferred is a 32-bit
|
| 647 |
|
|
; integer
|
| 648 |
|
|
;
|
| 649 |
|
|
; START - indicates that a new Am29027 operation is to be started
|
| 650 |
|
|
; once the operand has been transferred
|
| 651 |
|
|
;
|
| 652 |
|
|
;
|
| 653 |
|
|
; USAGE:
|
| 654 |
|
|
;
|
| 655 |
|
|
; cp_write_r reg [,LSB_reg] [,START] for floating-point operands
|
| 656 |
|
|
; or cp_write_r reg, INT [,START] for integer operands
|
| 657 |
|
|
;
|
| 658 |
|
|
; Transferring double-precision floating-point operands - Either of
|
| 659 |
|
|
; two forms is acceptable:
|
| 660 |
|
|
;
|
| 661 |
|
|
; cp_write_r reg
|
| 662 |
|
|
; or cp_write_r reg, LSB_reg
|
| 663 |
|
|
;
|
| 664 |
|
|
; If LSB_reg is omitted, the LSBs are taken from the next g.p.
|
| 665 |
|
|
; register.
|
| 666 |
|
|
;
|
| 667 |
|
|
; Ex: cp_write_r lr2 Transfers the contents of lr2 to
|
| 668 |
|
|
; the most-significant half of Am29027
|
| 669 |
|
|
; register R, and the contents of lr3
|
| 670 |
|
|
; to the least-significant half.
|
| 671 |
|
|
;
|
| 672 |
|
|
; cp_write_r lr2,lr5 Transfers the contents of lr2 to
|
| 673 |
|
|
; the most-significant half of Am29027
|
| 674 |
|
|
; register R, and the contents of lr5
|
| 675 |
|
|
; to the least-significant half.
|
| 676 |
|
|
;
|
| 677 |
|
|
;
|
| 678 |
|
|
; Transferring single-precision floating-point operands - Use the
|
| 679 |
|
|
; form:
|
| 680 |
|
|
;
|
| 681 |
|
|
; cp_write_r reg
|
| 682 |
|
|
;
|
| 683 |
|
|
;
|
| 684 |
|
|
; Ex: cp_write_r lr2 Transfers the contents of lr2 to
|
| 685 |
|
|
; the most-significant half of Am29027
|
| 686 |
|
|
; register R, (the contents of lr3
|
| 687 |
|
|
; will be transferred to the least-
|
| 688 |
|
|
; significant half of register R, but
|
| 689 |
|
|
; these bits are don't cares).
|
| 690 |
|
|
;
|
| 691 |
|
|
;
|
| 692 |
|
|
; Transferring integer operands - Use the form:
|
| 693 |
|
|
;
|
| 694 |
|
|
; cp_write_r reg,INT
|
| 695 |
|
|
;
|
| 696 |
|
|
;
|
| 697 |
|
|
; Ex: cp_write_r lr2,INT Transfers the contents of lr2 to
|
| 698 |
|
|
; the least-significant half of Am29027
|
| 699 |
|
|
; register R, (the contents of lr2
|
| 700 |
|
|
; will also be transferred to the most-
|

; significant half of register R, but
|
| 702 |
|

; these bits are don't cares).
|
| 703 |
|
|
;
|
| 704 |
|
|
;
|
| 705 |
|
|
; Starting an Am29027 operation - Any of the forms above may be
|
| 706 |

|
; USAGE:
|
| 2073 |
|
|
;
|
| 2074 |
|
|
; cp_build_inst reg,op_code,[precision,]dest,source1[,source2][,source3]
|
| 2075 |
|
|
;
|
| 2076 |
|
|
; Op-codes fall into two categories: those that correspond to Am29000
|
| 2077 |
|
|
; floating-point op-codes, and for which the precision is implicit (e.g.
|
| 2078 |
|
|
; FADD, DMUL); and those that correspond to Am29027 base operations
|
| 2079 |
|
|
; (e.g. P_PLUS_T, P_TIMES_Q), and which require an explicit precision
|
| 2080 |
|
|
; specification.
|
| 2081 |
|
|
;
|
| 2082 |
|
|
; Every operation specified must have a destination; if the operation
|
| 2083 |
|
|
; does not write a result to the Am29027 register file, destination GP
|
| 2084 |
|
|
; must be specified. The number of source operands specified must agree
|
| 2085 |
|
|
; with the number of source operands required by the operation specified.

; USAGE:

|
|
;
|
| 2443 |
|
|
; cp_build_inst_h reg,op_code,[precision,]dest,source1[,source2][,source3]
|
| 2444 |
|
|
;
|
| 2445 |
|
|
; This macro is similar to cp_build_inst, but creates only the 16 MSBs
|
| 2446 |
|
|
; of the 32-bit Am29027 instruction word. This macro is useful in cases
|
| 2447 |
|
|
; where the 16 LSBs of instruction word, which specify the operation
|
| 2448 |
|
|
; to be performed, already exist in an Am29000 g.p. register, but where
|
| 2449 |
|
|
; the 16 MSBs, which specify operand sources and destination, must be
|
| 2450 |
|
|
; changed. In such cases, one Am29000 instruction can be saved by using
|
| 2451 |
|
|
; cp_build_inst_h instead of cp_build_inst.
|
| 2452 |
|
|
;
|
| 2453 |
|
|
; Syntax and usage are identical to that of cp_build_inst.
|
| 2454 |
|
|
;
|
| 2455 |
|
|
; NOTE: This macro references macro _cp_set_op_params, which appears
|
| 2456 |
|
|
; in the assembly listing for macro _cp_build_inst.

;
|
| 2743 |
|
|
; This macro is similar to cp_build_inst, but creates only the 16 LSBs
|
| 2744 |
|
|
; of the 32-bit Am29027 instruction word; the 16 MSBs of the target
|
| 2745 |
|
|
; register are set to 0. This macro is useful in cases
|
| 2746 |
|
|
; where it is helpful to specify instruction LSBs and MSBs separately,
|
| 2747 |
|
|
; to improve instruction scheduling.
|
| 2748 |
|
|
;
|
| 2749 |
|
|
; Syntax and usage are identical to that of cp_build_inst.
|
| 2750 |
|
|
;
|
| 2751 |
|
|
; NOTE: This macro references macro _cp_set_op_params, which appears
|
| 2752 |
|
|
; in the assembly listing for macro _cp_build_inst.
